Hi everyone,
Planning to do some aero testing with some cardboard this winter with my MR2. I don't have time to tuft test just now but I figure doing a template overlay is a good first step...except I don't have a clue as to how to do this with my softtop!
Here's a good side shot of a Spyder:

The 2nd last hoop and last hoop form a nice angle that you'd expect from the end of a roof, but I don't know if I should treat it differently. At highway speed the fabric tends to lift up a little so it doesn't look as bumpy.
